As you can all see the plants are all drooping except for one and the rest are starting to spot and yellow I know this condition can kill plants extremely quickly. I have turned off the 600 watt hps bulb that I use for there light in there and am just giving them general hydroponics micro and veg nutrients. I replaced the water with 13 gallons of spring water and a half a tsp of both kinds of nutrients. I know about nutrient lock out and such but how do I revive them they are all drooping but one and yellowing extreme care and help is needed.
